The Goodyear Assurance radial featuring ComforTred Technology is a premium Passenger All-Season tire designed to bestow Goodyear's ultimate ride comfort to the drivers of luxury coupes and sedans. It was developed to combine long wear with year-round traction, including light snow. On the outside, the Assurance ComforTred radial features a symmetric tread design that uses a system of densely packed tread blocks to offer a smooth, quiet and comfortable ride. A super-shock absorbent layer of rubber sandwiched between the tread and steel belts (that provides on average 20% more cushion than standard auto tires) insulates vibration and impacts with expansion joints, potholes and bumps.
